THRESHlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent N 0. 767,915, dated August 16, 1904. Application filed June 3, 1903. Serial No. 159,972. (No model.)

To all whom it may concern: I

Be it known that I, HENRY SoHLEUsNER, a citizen of the United States, residing at Garner, in the county of Hancock and State of Iowa, have invented new and useful Improvements in Threshing-Machines, of which the following is a specification.

My invention relates to new and useful iml provements in threshing-machines, and more particularly to grain-separators for use in connection therewith. Its object is to provide rotary means for stripping the straw and for separating the grain therefrom, said means being simple, durable, and inexpensive in construction and adapted to be easily operated.

With the above and other objects in view the invention consists in providing a threshing-machine with a cylinder having teeth upon the periphery thereof, and this cylinder is adapted to engage the straw and throw it upward into contact with a deflector which serves to deflect the material downward upon a rapidly-rotating separating-cylinder. A retarding-cylinder rotates slowly adjacent the separating-cylinder, and the material is adapted to be combed and stripped between teeth upon the separating and retarding cylinders out of the path of the teeth thereon. A second shaft 6 is journaled within the body 1 and has a separating-cylinder 7 thereon, from the periphery of which extend teeth 8. A sprocket 9 is arranged on the shaft 6, and a similar sprocket 10 is secured to the shaft 2. A chain 11 extends over these two sprockets and also over idlers 12, which are arranged at opposite sides of a large sprocket 13, secured to a shaft 14, on which is arranged a retarding-cylinder 15. This cylinder is located close to the upper portion of the separating-cylinder and has sharp prongs or teeth 16 extending from the periphery thereof and adapted to work between the teeth 8 on the cylinder 7. A deflector-plate 17 is secured to the deck 18 of the threshing-machine and so located asto direct downward upon the separating cylinder 7 the material thrown thereagainst by the cylinder 3.

A curved grate 19 is concentric with and incloses the lower half of the separating-cylinder 7, and this grate is formed of parallel V-shaped bars 20, as shown in Fig. 2. Arranged on these bars are preferably two parallel rows of projections 21, which are arranged between paths of teeth 8 on cylinder downward over a grate of pe- 7 and are adapted to retard the passage of culiar construction, where the grain is sepamaterial over the grate. A deflecting-plate rated from the straw and discharged by grav- 22 is arranged below the retarding-cylinder ity into a grain-pan provided therefor. 15 and adjacent the inner end of the grate 19,

The invention also consists in the novel conand a retarding-plate 23 is also arranged adstruction. combination, and arrangement of jacent the opposite end of the grate 19, and parts hereinafter more fully described and these two plates serve to direct grain downclaimed, and illustrated in the accompanying ward to a pan 24 provided therefor. drawings, showing the preferred form of my In operation the material is supplied to the invention, and in whicl cylinder 3 in any desired manner, and as this Figure l is a vertical section through the cylinder rotates very rapidly it will engage separating mechanism employed in connection the material and will. throw it upward against with athreshing-machine, and Fig. 2 is a plan deflector-plate 17 by which it will be directed view of the grate with the separating-cylin downward adjacent to the pass between the der removed. cylinders 7 and 15. As the cylinder 7 rotates Referring to the figures by numerals of refvery rapidly and the cylinder 15 rotates slowly, erence, 1 is the body of a threshing-machine, it is obvious that the material engaged by the within which is journaled a shaft 2, having a teeth 8 and. 16 of the two cylinders will be throwing-cylinder 3 thereon, which is procombed or stripped thereby and carried over vided with teeth 4 extending from its periphthe grate 19. The projections 21 serve to reery. 'A curved bed or guide plate 5 is artard the movement of the material over the ranged under the cylinder 3, so as to prevent grate. The grain will fall down between the the material fed to the cylinder from falling bars 20 of the grate and upon the pan 24, and

should any 01 the grain be thrown outward from points adjacent the ends of the grate it would be deflected downward into the pan by plates 22 and 23. The straw after leaving the grate can be directed in any desired manner to a suitable receptacle provided therefor.

In the foregoing description l have shown the preferred form of my invention; but I do not limit mysel't' thereto, as l am aware that modifications may be made therein, and I. therefore reserve the right to make such changes and alterations as may 'lairly fall within the scope of my invention.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. In separating devices for threshing-machines, the combination of a throwing-cylinder, a separating-cylinder, a retarding-cylinder disposed between said cylinders, and near- 1 est to said separatirig-cylinder, the latter hav ing teeth thereon, a deflector located in the path of the material o1 ei"ated upon by the throwing-cylinder, and above the pass between the separating and retardingcylinders, means for rotating the several cylinders mentioned at ditlerent speeds, and a curved grate concentric with and located beneath said separatiug-eylinder,said grate having parallel projections thereon between which the teeth on the separating-0ylinder work.

2. ln separating devices for threshing-machines, the combination of a toothed throwingcylinder, a toothed separating-cylinder, a toothed retarding-cylinder disposed between said cylinders, and nearest to said separatingeylinder, the teeth of said retarding-cylinder working between the teeth of said sermratingcylinder, a deflector disposed in the path of the material operated upon by the throwingcylinder, and above the pass between the separating and retarding cylinders, a curved grate beneath said separating-cylinder, another deflector beneath the retarding-cylinder and adjacent to the inner end of the grate, a retarding-1 )late adjacent to the outer end of said grate, and means for operating the several cylinders mentioned at different speeds.

.l n testimony whereof I aflix my signature in presence of two witnesses.
